You could see Brandon Marshall’s excitement as soon as he came to the line in the second quarter and saw no one covering him. Marshall began signaling to quarterback Ryan Fitzpatrick, who also saw the Tennessee defensive mix-up.

Fitzpatrick, lined up in the shotgun, hurried under center and Nick Mangold snapped it to him. He threw it to Marshall, who ran 69 yards for a touchdown that gave the Jets a 27-0 lead.

“It could have been a disaster before it started with Nick still snapping it as a shotgun snap,” Fitzpatrick said. “He realized it as well, gave me the snap as if I was under center, got it clean, threw it out there to Brandon.”

The Titans said their headsets were malfunctioning at the time and they could not get the defensive call in.

“It’s huge, just huge,” Titans interim coach Mike Mularkey said of the play.

“Our headsets went down that series prior to running out there so there was no communication to upstairs or to the linebackers,” Mularkey said. “So again, not an excuse, but we had no communication to the field or upstairs. And that doesn’t give us any reason not to still cover an uncovered receiver.”

Mangold said he could sense the play as it was developing and complimented Fitzpatrick’s recognition of it.

“The force is strong with that one. You could just feel it,” Mangold said.

Marshall said it may have been the easiest touchdown he’s scored.

“I’ve got to think about it, but that was a really easy touchdown and I’ll take it, man,” he said.

Rookie WR Devin Smith suffered what appeared to be a serious right knee injury in the third quarter on a punt. He needed to be carted off the field. Smith will have an MRI exam Monday to determine the extent of the injury.

Marshall and Eric Decker are attacking the Jets’ record books. Marshall has 1,186 yards this season, which is seventh all-time in team history. The record is 1,434 yards by D on Maynard in 1967.

He has 89 catches, four shy of Al Toon’s club record set in 1988. His 11 receiving touchdowns are three shy of the record held by Maynard (1965) and Art Powell (1960).

Decker has 14 touchdowns over his two seasons as a Jet, the third most over anyone’s first two Jets seasons. They are the first duo to each have nine touchdowns in the season and their 20 combined touchdowns ties them for first all time among duos with Powell/Maynard in 1960 and Toon/Wesley Walker in 1986. … CB Darrelle Revis returned after missing two games with a concussion. … CB Marcus Williams missed his second straight game with an MCL sprain. … WR/PR J eremy Kerley left the game with a calf injury.
